Ontario's regulated iGaming market closed out 2025 with its strongest annual performance since launching in 2022, according to data released by iGaming Ontario (iGO). Total cash wagers reached approximately CAD $98.3 billion — up 26% year over year — while non-adjusted gross gaming revenue (NAGGR) climbed to just over CAD $4 billion, representing a 34% increase from the prior year.
The milestone marks a watershed moment for the province's competitive iGaming model, which has now generated cumulative tax revenue of more than $2.04 billion for Ontario over the nearly four-year period since launch.
Monthly Records Fell Throughout the Year
2025 wasn't just a strong year — it was a record-breaking one, month after month. Wagering topped CAD $9 billion in each of the final three months of the year, with December's handle reaching an all-time high. December also saw monthly NAGGR cross the $400 million threshold for the first time, settling at CAD $425.4 million.
Breaking down the revenue by segment, online casinos accounted for roughly 75% of total market revenue — operators finished the year with more than CAD $3.1 billion in casino-specific revenue. Sports betting, meanwhile, brought in CAD $141 million in handle and CAD $5.8 million in revenue in December alone, representing about 1.4% of total market totals.
More Players, More Active Accounts
Behind the headline numbers is a simple story: more Ontarians are gambling online, and more of them are doing so on regulated, AGCO-licensed platforms. iGO reported a steady increase in monthly active accounts throughout 2025, with February showing a significant jump compared to January — marking roughly a 32% increase from the same period the previous year.
A channelization survey conducted by Ipsos in April 2025 found that 83.7% of Ontarians who gambled online in the past three months reported wagering on a regulated website. That means roughly one in six online gamblers in Ontario is still using unregulated or grey-market sites — a concern for regulators as the market matures.
What This Means for Ontario Players
The growth of the regulated market has real consequences for Ontario players. Tax revenue from iGaming flows back into provincial priorities — healthcare, education, and responsible gambling programs. The AGCO's oversight ensures that licensed operators offer fair games, transparent bonus terms, and player protections that unregulated sites simply don't provide.
For players, the competitive environment between operators also means better bonuses, more game variety, and improved user experiences. Ontario's open market model — which allows multiple licensed operators to compete — has been credited with driving those improvements since launch.
Regulatory Changes on the Horizon
While the revenue numbers are historic, the regulatory landscape continues to evolve. The iGaming Ontario Act, 2024 — enacted through Schedule 9 of Bill 216 — came into force on May 12, 2025, restructuring iGO as a fully independent corporation no longer operating as a subsidiary of the AGCO. That structural change is expected to sharpen iGO's focus on market development and player protection.
The AGCO itself has been refining its standards. In July 2025, the regulator updated its responsible gambling training requirements for casino and lottery employees, removing the need for Registrar approval of individual training programs and adopting a more flexible, outcomes-based approach. The move was designed to reduce red tape while maintaining Ontario's high standards for player protection.
Where the Market Goes from Here
With four years of data now behind it, Ontario's iGaming market shows few signs of slowing. Monthly active accounts continue to climb, total wagers are trending upward, and the tax revenue generated for the province has become a meaningful line item in provincial finances.
The remaining challenge — and it's a significant one — is that 16% channelization gap. Bringing the roughly one in six players currently on unregulated sites over to regulated, AGCO-licensed platforms remains a stated priority for both iGO and the AGCO. Until that gap closes, some portion of Ontario's gambling revenue will continue flowing to operators outside the province's regulatory reach.
For Ontario players, the message remains straightforward: stick to licensed operators, read the bonus terms carefully (our wagering requirements guide can help with that), and take advantage of the responsible gambling tools that regulated sites are required to offer. The numbers show Ontario's iGaming market is growing fast — but growing responsibly is the more important metric.
